RK3399 and RK3288 shared the same eDP IP controller, only some light
difference with VOP configure and GRF configure.

Changes in v4:
- Improved the overly complicated .atomic_check function. (Sean)
- Add reviewed flag from Tomasz

Changes in v3:
- Give the "rk3399-edp" a separate line for clarity in document (Tomasz, reviewed at Google Gerrit)
    [https://chromium-review.googlesource.com/#/c/346314/10/Documentation/devicetree/bindings/display/rockchip/analogix_dp-rockchip.txt@5]
- Move 'output_type' setting before the return statement (Tomasz, reviewed at Google Gerrit)
    [https://chromium-review.googlesource.com/#/c/346314/10/drivers/gpu/drm/rockchip/analogix_dp-rockchip.c@154]
- Add the acked flag from Mark.
